Back in August I took a look at the new WD My Passport SSD and was impressed with its performance and form factor. While it does have an SSD inside it wasn’t really designed to take a beating, something that might happen when you use a drive a lot and it gets tossed around. Well, Western Digital owns SanDisk as well and along with the My Passport SSD they had also sent over the SanDisk Extreme 510 Portable SSD. It is a completely different design and it is designed to handle a little more rough handling. Today I’m going to check it out and see what they are doing differently with this model and take a look at its overall performance.
